摘　　要：分析了950热连轧机生产1.8mm×800mm薄带钢的技术难点,制定了详细的产品试制方案。针对试生产中出现的废钢、板形不良、尺寸超差、塔形等问题,通过严格控制温度、优化侧导板和活套以及卷取机参数、优化轧机负荷分配、投入液压AGC和弯辊功能、采用负辊型等措施,解决了生产中的技术难题,产品成材率97.6%,综合合格率99.8%,已转入批量生产。The technological difficulty of predueing 1.8mm × 800mm strip steel by 950 hot tandem mill is analyaed and detailed trial scheme of the products is made. Aiming at the troubles appeared in trial operation such as steel scrap appearance, flatness badness, dimension out-of-tolerance and telescoping etc, through controlling the temperature strictly, optimizing the parameters of the side guide, loop, coiling machine and the load distribution of the mill, adding the functions of hydraulic AGC and roll bending and adopting concave camber, the teehnohgieal difficulties in production are settled. Then rolling yield is 97.6%and compesitive percent of pass is 99.8%. Now the products are put into batch production.
